purely speculation, but maybe about $5 or $6 will be bottom ?then buy ?

Expect false rallies from the bottom. You might be tempted to buy too soon. Back in April before the bitcoin bubble, one could buy a bitcoin for $1 or less.

The bitcoin market, as opposed to the bitcoin economy, must become unloved and neglected - the bottom can be expected to have relatively low volume, an absence of speculators, mostly merchants, customers and miners conducting routine transactions.

I feel we're going to pay a pizza ten grands BTC again soon. Even if it seems that there is much further to drop, I am not selling my BTCs bought at 19.xx USD each for anything less that I paid it ... even if I will have to wait a couple of years or more to do it.Definitely I will stop mining if it drops below 10 USD.
